Better proofs
...
Proof graphs are now entirely stored in
the cpremise field of clauses

First changes for better persistent proofs
...
This commit ensures that clauses now contain
all necessary information to construct the proof
graph (without relying on propagation reasons).

Fix for semantic conflict and decision levels
...
When faced with a semantic conflict, a new decision
must be made to solve the conflict, however, because
we just backtracked, it is not ensured that the solver
is in a correct state to add a new level, so the decision
is now delayed until propagation has been done.

Fixed bug in if_sat

The trick using a bool ref to see if a new clause has been pushed
did not detect cases where new clauses were added using assume.

Removed special solver types module for pure SAT

This specialisation was there to have better performances,
but it doesn't seem to have any impact anymore.

Long explanation: when backtracking to level 0,
while already being at level 0, very strange
things might happen, most notably there might still
be facts left to propagate...
